Compile-time Initialization and Build
One of C++’s major advantages in embedded systems is its ability to perform compile-time computation. In most cases, we have significant knowledge about the application beforehand, allowing us to configure it at compile time. Intel’s CIB library provides a declarative interface for configuring firmware components during compilation.
As you saw in Chapter 15, the Observer design pattern is commonly used in event-driven systems to decouple the source of events (publisher) from the entities that react to those events (observers or subscribers). By using a subscriber interface, observers can register themselves with the event source, which then notifies them of changes or events without needing to know details about the observers’ implementations.
This decoupling allows for greater flexibility and modularity in system design, as components can be added, removed, or modified without tightly coupling them to the event generator...
